Hot Expanded Seamless Paipa
Ko te wera whakawhänui paipa maitai he wera whakawhänui putorino tuitui, i te mea iti kiato engari te contraction o te putorino maitai kaha (putorino tui) ka taea te kiia ko te roha waiariki.He tukanga o te hurihuri whiri, te tuhi tuhi ranei hei whakawhanui i te diameter paipa.Steel putorino thickening i roto i te wa poto o te wa, ka taea te whakaputa momo kore-paerewa, me te motuhake o ngongo tui ki iti-utu me te tiketike production tōtika, nga whanaketanga o te ao o nāianei i roto i te mara o te ngongo okeoke.
Hot whakawhänui putorino ko te whakawhänui i te diameter o te putorino ki te whakaoti tukanga - tukanga roha waiariki o te hanga o te putorino maitai.Ko te putorino roha wera kei te nuinga o te wa e kiia ana ki nga putorino maitai tuitui wera.

Te maimoatanga mata o te paipa maitai:
I roto i te tikanga ki te whakapai ake i te ora ratonga o te paipa hinu, te maimoatanga mata te nuinga o kawea i roto i ki te whakahaere i te huinga u o te paipa maitai me te anticorrosive coating.Common tikanga tukatuka e: horoi, taputapu derusting, pickling, pere ngingio derusting wha kāwai.
1 te horoi Ko te hinu, te puehu, te whakahinuhinu, te mea pararopi e piri ana ki te mata o te putorino rino, te nuinga o te whakamahi i te whakarewa, te whakaehunga hei horoi i te mata.Heoi, ko te waikura, te kiri waikura, me te para whakahiato i runga i te mata o te putorino maitai e kore e taea te tango, na etahi atu e hiahiatia ana nga tikanga maimoatanga.Tool rust removalSteel pipe mata waikura, waikura, fehokotaki'anga para, ka taea te whakamahi i te paraihe waea maitai ki te horoi me te whakakoi i te mata treatment.Tool derusting taea te wehea ki ā-me te mana, ka taea te derusting taputapu ā-Sa
Ko te taumata 2, ka taea te whakakore i te taputapu hiko ki te taumata Sa3. Mena ka piri te mata o te paipa rino ki te kiri waikura tino kaha, kaore pea e taea te tango i te waikura me te awhina o nga taputapu, na me rapu etahi atu huarahi.
3 pickling Ko nga tikanga pikinga noa ko te matū me te electrolysis.Engari ko te tiki matū anake e whakamahia ana mo te tiaki i te waikura paipa.Ka taea e te pikau matū te whakatutuki i tetahi tohu o te ma me te taratara i runga i te mata o te paipa maitai, he pai mo nga raina punga o muri. pupuhi (kirikiri) i muri i te tukatuka ano.
4 pupuhi pupuhi mo te tango waikuraNa te motuka mana nui te taraiwa tere tere tere, te kirikiri rino, te pupuhi rino, te waahanga, nga kohuke me etahi atu waea abrasive i raro i te mahi o te kaha centrifugal i runga i te rehu paipa rino me te pupuhi papatipu, tino tango i te waikura, waikura. me te paru i runga i tetahi ringa, i runga i te tahi atu te ringa, paipa maitai i raro i te mahi o te abrasive pānga tutu me te kaha waku, ki te whakatutuki i te roughness kākahu e hiahiatia ana.I roto i nga tikanga maimoatanga e wha, pupuhi ngingio me derusting ko te tikanga maimoatanga pai mo te putorino derusting.Ko te tikanga, ko te pupuhi pupuhi me te whakakore i te nuinga o te waa e whakamahia ana mo te maimoatanga mata o roto o te putorino maitai, a ko te pupuhi pupuhi me te pupuhi ka whakamahia mo te maimoatanga mata o waho o te putorino maitai.
